... turn radius. this is what I am attempting to replicate. So any help or advise will be most welcome, I guess my main problem is I am a model railroader not a model engineer. hence the lack of understanding of chain lengths and such posted: 10 Dec 2007 09:30 from: Templot User -- --- from Andy Reichert -- --- For the 13 ft radius turnouts, you could use the ORR HO US tram turnouts and crossings in Code 100. See the Orr section on Trolleyville.com A UK M/F, Tramalan, has done copies in white metal. I think there is web site of the same name. Both are girder rail, but then you probably need continuous guard rails at those radii anyway.
